Stepan,
AFAIK Map type did always behave correctly on client side, as it does
now. This is a corresponding piece of my test suite:
```
def test_put_get_map(client):
cache = client.get_or_create_cache('test_map_cache')
cache.put(
'test_map',
(
MapObject.HASH_MAP,
{
(123, IntObject): 'test_data',
456: ((1, [456, 'inner_test_string', 789]),
CollectionObject),
'test_key': 32.4,
}
),
value_hint=MapObject
)
value = cache.get('test_map')
assert value == (MapObject.HASH_MAP, {
123: 'test_data',
456: (1, [456, 'inner_test_string', 789]),
'test_key': 32.4,
})
```
Or is there another, more specific problem with maps?

Dmitry,
Great, checked, now all things woks well
Hope that Igor made review for this PR
But what about Maps? Looks like different ticket? or it can be done in
same
ticket scope?

Stepan,
Sorry, I forgot to update from upstream prior to start working on this
issue, and thus brought a regression. My bad. Just merged with the
latest master. Please, check it out again.

Stepan,
Thank you for your great job in evaluating Python thin client, as
well
as other thin clients.
There was indeed a bug in Python client regarding the handling of
type
hints in Collection type. I created a fix and did a PR under
IGNITE-10358 task, but the same PR is also fixes the problem in
IGNITE-10230 task.
As of handling the type mapping in gists you provided, I left
comments
on both tasks.

Dmitry, Alexey
Thank you for help, this answers help me a lot with understanding
how
clients are work
Not so long time ago i met problem which is have expected behavior,
but
its
may broke some workflows in future for some users
Its all about not specified data types in collections and map's
All description and examples in
https://issues.apache.org/jira/browse/IGNITE-10358
Dmitry, can you have a quick look at it and maybe in future somehow
fix
it?

Stepan!
TL/DR: what you got with Python client in your gist is an intended
behavior.
Explanation: As per docs, Object array contains of type ID (which
is
defaults to -1) and an array of objects.
https://apacheignite.readme.io/docs/binary-client-protocol-data-format#section-object-array
Your gist might be fixed accordingly:
```
from pyignite import Client
from pyignite.datatypes import *
OBJECT_ARRAY_TYPE_ID = -1
OBJECT_ARRAY_CONTENTS = [1, 2]
client = Client()
client.connect('127.0.0.1', 10800)
cache = client.get_or_create_cache("PY_OBJECT_ARRAY")
cache.put(
1,
(OBJECT_ARRAY_TYPE_ID, OBJECT_ARRAY_CONTENTS),
key_hint=IntObject,
value_hint=ObjectArrayObject,
)
# Python output: print(cache.get(1))
# (-1, [1, 2])
```
The situation is similar with Map and Collection, they have types.
Types
and type IDs are mostly useless in Python, but I left them for
interoperability reasons. If you think I should kick them out, just
let
me know.
The usage of these 3 data types is documented and tested. You can
refer
to the table in “Data types” section:
https://apache-ignite-binary-protocol-client.readthedocs.io/en/latest/datatypes/parsers.html
The tests are here:

Hi, everyone
Create new thread to centralize cross compatibility and others
common
problems between thin clients
Tying to use Object array to exchange different data between JS,
PHP
and
Python thin clients
JS and PHP simply can't put any type of arrays
Python can put data, but if you take it, data would be completely
different, maybe during this put process data is changed
Code and output:
PHP -

I'm tried different data types (string, double, float, complex
objects,
just random objects, char, byte, Date), still
How, from my perspective, it should works:
put array of any type and then get this array.
Example: put [1,2,3] -> get [1,2,3] or put [new Date(), new
Date()]
->
get [[Date object], [Date object]] (like in java thin client)
Looks like bug in all clients, what you think?
I wanted to try Collections, but i think this type have same
problem
